Legal and regulatory compliance

Legal and regulatory compliance is a critical topic for the CISSP exam, particularly as it relates to the eighth domain: Security and Risk Management. Understanding the legal frameworks, standards, and regulations that impact cybersecurity is essential to protect information and manage risk.

Key Legal Concepts for CISSP

1. Intellectual Property (IP) Law

IP law refers to the protection of creations of the mind, such as inventions, designs, and artistic works. The major types of IP that relate to cybersecurity are:

  • Copyright: Protects original works of authorship (software code, music, books, etc.). It gives the creator exclusive rights to reproduce, distribute, and perform their works.
  • Patent: Grants exclusive rights to inventors to use, sell, or license an invention for a specified period, typically 20 years. Software-related patents, like algorithms, are controversial in some jurisdictions.
  • Trademarks: Protect symbols, logos, and names used to distinguish goods or services.
  • Trade Secrets: Protect proprietary information or processes that are valuable to a company (e.g., formulas, algorithms). Unlike patents, trade secrets don’t expire but require ongoing protection (non-disclosure agreements, etc.).

2. Privacy Laws and Regulations

Privacy laws regulate how organizations collect, store, and use personal data. These regulations vary widely across regions and sectors. Some of the most important privacy regulations include:

  • General Data Protection Regulation (GDPR): The GDPR is a comprehensive privacy regulation that applies to the European Union (EU) and provides individuals with rights over their personal data. It includes principles such as data minimization, transparency, and the right to be forgotten. Heavy fines can be imposed for non-compliance.
  • California Consumer Privacy Act (CCPA): This law enhances privacy rights and consumer protection for residents of California. It gives California residents the right to know what personal data is being collected about them and the right to request the deletion of that data.
  • Health Insurance Portability and Accountability Act (HIPAA): A U.S. law that requires healthcare providers to protect the confidentiality and security of healthcare information (Protected Health Information, PHI).
  • Children’s Online Privacy Protection Act (COPPA): U.S. law designed to protect the privacy of children under 13, focusing on websites and online services.
  • Family Educational Rights and Privacy Act (FERPA): Protects the privacy of student education records in the United States.
  • Electronic Communications Privacy Act (ECPA): Regulates how electronic communications (e.g., email, phone calls) are intercepted and monitored.

3. Compliance with International Laws

In today’s global environment, companies must often comply with international laws when conducting business across borders. This includes regulations like the GDPR and other regional privacy laws. Understanding the extraterritorial impact of laws is critical for CISSP professionals, as laws like GDPR apply even if a company is not located in the EU but processes the data of EU citizens.

4. Computer Crime Laws

Computer crime laws cover offenses related to hacking, unauthorized access, and computer fraud. Some key laws include:

  • Computer Fraud and Abuse Act (CFAA): A U.S. law that makes it illegal to access a computer without authorization or exceed authorized access. This law applies to hacking, creating malware, and other forms of cybercrime.
  • Electronic Communications Privacy Act (ECPA): Protects communications like email, telephone conversations, and data stored electronically from unauthorized access and wiretapping.
  • Cybersecurity Information Sharing Act (CISA): Encourages information sharing between government and private organizations to combat cybersecurity threats.

5. Transborder Data Flow

Transborder data flow involves the movement of personal, sensitive, or confidential data across national borders. Different countries have different laws governing this, and managing compliance with these laws is critical for multinational organizations.

For example:

  • GDPR imposes strict rules on transferring personal data outside the EU.
  • Data Localization Laws in countries like China and Russia require certain types of data to be stored within the country.

6. Legal Issues in Incident Handling

Legal concerns arise when responding to security incidents, particularly if they involve breaches of personal data or intellectual property theft. Some key issues include:

  • Chain of Custody: Proper handling and documentation of evidence during investigations to ensure its integrity in court.
  • Breach Notification Laws: Many jurisdictions (e.g., GDPR, CCPA) require organizations to notify affected individuals and regulatory bodies in the event of a data breach.
  • Forensics: Ensuring that any digital evidence collected for legal proceedings adheres to the legal standards for admissibility in court.
  • Liability: Organizations can face legal liability for failing to prevent or respond adequately to cybersecurity breaches.

7. Ethical Considerations in Cybersecurity

The (ISC)² Code of Ethics is a key aspect of the CISSP exam, focusing on the responsibilities of cybersecurity professionals to:

  • Protect society, the common good, and the infrastructure.
  • Act honorably, honestly, and legally.
  • Provide diligent and competent service to stakeholders.
  • Advance and protect the profession.

8. Legal vs. Regulatory vs. Standards

  • Laws: Mandated by the government and have the force of law.
  • Regulations: Issued by government agencies to enforce laws. They provide the specifics of compliance requirements.
  • Standards: Non-mandatory guidelines that promote best practices (e.g., ISO/IEC 27001 for Information Security Management Systems).

Common Security-Related Regulations and Standards

1. SOX (Sarbanes-Oxley Act)

  • A U.S. law enacted to improve the accuracy and reliability of corporate financial reporting. SOX has significant IT security requirements, especially regarding the integrity of financial data and systems.
  • Section 404 requires organizations to establish internal controls for financial reporting, which can extend to IT systems.

2. PCI DSS (Payment Card Industry Data Security Standard)

  • A set of security standards designed to ensure that companies that process, store, or transmit credit card information maintain a secure environment.
  • Compliance Requirements: Encryption, firewalls, access controls, vulnerability management, and monitoring.

3. FISMA (Federal Information Security Management Act)

  • A U.S. law that applies to federal agencies and contractors, requiring them to implement comprehensive security programs to protect government information and systems.

4. ISO/IEC 27000 Series

  • A family of standards for managing information security. ISO/IEC 27001 is the most widely recognized standard for an Information Security Management System (ISMS).

5. NIST (National Institute of Standards and Technology) Frameworks

  • The NIST Cybersecurity Framework provides guidelines for managing and reducing cybersecurity risks, particularly for critical infrastructure organizations.
  • NIST SP 800-53: A widely used standard for security and privacy controls for federal information systems.

CISSP Exam Focus on Legal and Regulatory Compliance

When preparing for the CISSP exam, the following topics within the Legal, Regulations, Investigations, and Compliance domain are critical:

  • Recognizing the differences between various laws, regulations, and standards (local, national, and international).
  • Understanding privacy requirements and how they apply to information systems.
  • The ability to analyze and determine the impact of regulatory requirements on security policies and procedures.
  • Legal concepts related to computer crimes, including data breach notification requirements and intellectual property law.
  • Investigating security incidents while adhering to laws on evidence handling, forensics, and chain of custody.

Conclusion

Legal and regulatory compliance is a key area of the CISSP exam. Candidates need to understand a broad array of laws, regulations, and standards that impact cybersecurity operations. This includes privacy laws like GDPR, intellectual property rights, computer crime laws, and regulatory frameworks such as PCI DSS and SOX. Familiarity with incident response legal issues, international data protection laws, and ethical standards is essential to navigating this domain successfully.
